One thing my mother often makes during the summer is Kong Guksu, noodle in soy milk.

You can do it with plane soybean milk. It may be a bit of stretch for non-Korean that eating noodle in soy milk, but remember pasta in cream sauce? It is same concept. :)
I did it in traditional way; sock and boil soy beans, ground it as silky as possible and add salt & pepper. The process takes a bit long, but it is wonderful meditation for me.
The short cut for making broth is blend a table spoon of peanut butter, salt & pepper to your taste with plane cold soy milk in blender. Add cooked and chilled wheat noodle of your choice.
I didn't like this rather bland noodle. My taste was too young to appreciate it. Suddenly, after 30 and some more years, I discover it as if it is new food! Some times, good things take time to be appreciated.
